No Drawing.

To all whom it may concern: Be it known that I, ALFRED ADAMS, Jr.,acitizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvama, have invented new and usefulImprovements in Flexible- Leather-Board Composition, of which thevfollowing is a specification.

' My invention relates to a new and useful composition of matter for"producing flexible leather board to be used in the manufacture ofshoes, mats, chair bottoms, upholstery and similar articles.

With these ends in view, this invention consists in the details andcombination of elements hereinafter set forth and specificallydesignated by the claims In order that those skilled in the art to whichthis invention appertains, may understand how to make and use the same,I will describe the composition in detail.

In carrying out my invention I mix together hide and leather clippingsof ap-' proximately ninety pounds, to which is added approximately tenpounds of cotton,

f preferably in the raw state, to provide thenecessary fiber, and tothese is added any suitable and well known binder, such as amixture'madeof glycerin, and rubber glue, the whole mass being coloredto the desired shade-by adding thereto a suitable coloringpigment. Theseingredients after being I mixed together are beaten, 'shredded'andstirred to produce a homogeneousmassof A liquid, thin enough to flowreadi1y, aj sufii- Specification of Letters Patent.

cient amount of the binderbeing added to accomplish this result. Thisliquid mass is.

then poured into molds of the desired shape and subjected to hydraulicor other high pressure, afterwhich it is gradually dried by aslow heatto produce the flexible leather board.

Of course I do not wish to be limited to the exact details andcombinations'as herein described, as these may be varied within thelimits of the appended claims without departing from the spirit of myinvention.

Having thus fully described my invention, what I claim as new anduseful, is- 1. The herein described composition of matter for producinga flexible leather board consisting of a mixture of hide and leatherclippings, ninety pounds, cotton ten pounds and a liquid binder.
